JOSEPH R. H. HINTON, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE CONTINENTALSTORE SERVICE COMPANY, OF NEYV YORK, N. Y.

SPRlNG-ACTUATED DRUM.

EJPECIFICATIUN forming part of Letters Patent No. 329,836, datedNovember 3, 1885.

Application filed October 5, 1885. Serial No. 170,017. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH R. H. HINTON, a citizen of the UnitedStates, residing at Baltimore, Maryland, have invented new and use fulImprovements in Spring-Actuated Drums, of which the following is aspecification.

This invention relates to certain improvements in store-serviceapparatus of the class in which the cars carrying the cash or parcel runupon a way which is raised and lowered at one end to give the requiredinclination to the track, and the car taken from and restored to the wayby means of one rope; and the invention relates particularly to meansfor taking up the slack given the rope in the various op erations of thedevice. Heretofore some difficulty has been experienced in the use ofthese devices, caused by the swaying to and fro of the rope when slack,and its consequently imperfectly winding upon the drum intended for itsreception; also, no convenient means has been provided for locking thedrum upon which the rope is wound at any desired pointin its revolution.

The object of the present invention is to provide a drum for taking upthe slack of the operating-rope to be used in the same way as that shownin Patent N 0. 321,360, granted me on June 30, 1885, and which shallautomatically guide the slack of the operating-rope to the drum and windit thereon under all'circumstances; and, further, the object is toprovide simple means for locking the drum at any desired point in itsrevolution.

With these objects in view my invention con sists, essentially, of aspring-actuated drum having a grooved periphery and a guide fordirecting the cord to the said drum.

Further, the invention consists in a novel locking device combined wit-hsaid drum, consisting of a circular series of holes in the side of thedrum, entered by a spring-actuated pin mounted upon the standard uponwhich the drum is secured; and, further, the invention consists invarious details of construction, whereby the objects of the inventionare accomplished.

In order that those skilled in the art to which my invention relates maythoroughly understand the construction and advantages of the same, Iwill now proceed to describe it in con nection with the accompanyingdrawings, in which- Figure 1 is a side elevation of the device, thelockingpin being shown as in position to lock the wheel against turning.Fig. 2 is a central vertical section of the device, the section beingtaken in a line with and through the axle of the drum, the locking-pinbeing shown in full lines in a position to lock the drum againstturning, and the dotted lines showing the same drawn out to allow thewheel to turn; and Fig. 3 is a plan View, the dotted lines showing thedifferent positions of the lever for operating the locking-pin.

In the drawings, A represents a standard, preferably of cast-iron, andmade up of the base portion, a, which is fastened rigidly to the floor,and has a socket in its upper end, and the upper portion, b,which restsin the socket in the upper end of the base-section, and may be turnedtherein to bring the parts which are carried by the said upper portioninto any desired position relative to the apparatus which it is used inconnection with. This upper portion is held in any position to which itmay be turned by means of the setscrew c, which projects through theshell of the socket in the top of the section a, and bears against thelower end of the section b.

B represents a pin, which is set at right angles to the standard andsecured thereto by means of a set-screw, d,which passes through thestandard and bears against the said pin and holds it in place. The upperportion,b,of the standard is made thicker at the point where the pin Benters than at any other point for the purpose of qualifying it tosuccessfully withstand the strain which may be imposed there. Upon thispinB is mounted the wheel or drum 0, which is provided with the groovedperiphery D, for the reception and retention of the rope which is woundupon it. This drum is provided with a central chamber which is closed bya plate, M, and in this chamber I place the coil-spring L, one end ofwhich is fixed to the pin B and the other end to the side of thechamber, so that as the cord or wire is drawn from the drum the springis contracted,and its resiliency serves to turn the drum in the oppositedirection.

With a view to the prevention of imperfect ICC winding of the cord uponthe drum, caused by throughwhich the cord passes in being wound upon ordrawn from the drum.

The preferred means of attaching the end of the operating-rope to thedrum is shown in Figs. 1 and 2 of the drawings. This consists inproviding the tread and the central portion of the wheel with holes 6and f, respectively, through which the rope is passed and secured at theside of the wheel bya button, cross-pin, or the like.

The means for securing the wheel against turning will now be described.The side of the wheel 0 is provided with a circular series of holes, I,which are entered by a pin, H, mounted on the top of the standard. Thispin H is provided with a right-angular projection, F, for operatingthesame. A spring, G, is fastened at its lower end to the standard A, andits upper free end bears against the pin H, and constantly exerts atendency to force the said pin into any one of the holes in the wheelwhich may be opposite the pin.

In order that the pin may be capable of being withdrawn from contactwith the wheel by simply turning the right-angular portion F to one ofthe positions shown in dotted lines in Fig. 3, I provide that part ofthe standard with aprojecting portion, K, having its front face providedwith a V-shaped indentation, in the apex of which the vertical portion Frests when the pin is in engagement with the wheel 0. The

sides of the indentation are slightly curved outward, so that when thepin A is turned down at either side it will readily ride over the faceof the indentations and withdraw the pin.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A drum for use in connection with acash or parcel carrying apparatusof the kind described, provided with a grooved periphery, and a guidefordirecting the rope to the said periphery.

2. A drum for use in connection with store service apparatus of the kinddescribed, having a grooved periphery having combined therewith a guidefor directing therope to the said groove, and a locking device,substanprovided with pin B, andan opening nearits tially as described,for retaining the said drum at any desired point in its revolution.

3. A drum for use in connection with a storeservice apparatus of thekind described, having a grooved periphery, a coil-spring connected atone end to the drum and at the other to the pin on which the drum ismounted, and means, substantially as described, for locking the saiddrum at any point in its rotation.

4. In combination with the operating-rope of a store-service apparatusof the kind described, the drum provided with the groovedperiphery,thestandard A, which is made in sections, one turning in theother, and means, substantially as described, for locking the said drumat any desired point in its revolution.

5. The combination of the standard A, the; drum 0, provided with thegrooved periphery, and with a circular series of holes, and thespring-actuated locking-pin entering the saidholes for the purpose oflocking the said drum against turning;

6. The combination, with the standard A upper end for the passage of thelocking-pin, said opening having a V-shaped mouth, as de-. scribed, ofthe spring-actuated drum provided. with openings in the side, and thespring-actuated locking-pin, substantiallyas described. 7. Thecombination, with a store-service apparatus of the kind described, ofthe springactuated drum provided with the circular se-} ries of holes,the standard A, providedwith. the pin B, and the opening near the tophava ing the flaring mouth, the locking-pin having;v the upwardextension, and the spring E, .secured to the standard and bearingagainst the, pin, substantially as described.

8. The combination,with the standard A, of. the spring-actuated drummounted thereon and provided with the grooved periphery, and having theopenings in the periphery andside of the. said drum for the reception ofthe rope, substantially as described. l V In testimony whereof I havehereunto se t my hand in the presence of two subscribing 1 Witnesses:
